Update: New upgrade readiness tools for Office 365 ProPlus

We're planning to upgrade from Microsoft Office 2013 Professional Plus (32-Bit) to Office 365 ProPlus (64-Bit) on Windows 10. We see more issues relying on the ODBC/OleDB database connections used in MS Access and MS Excel.

I'm wondering, if these database connections will be reported, too? Especially, when they're using the Jet Engine (32-Bit) which doesn't exist for 64-Bit.

I have the same question for version dependant addins which are delivered by Microsoft itself? I.E. solver.xlam is referenced either in folder 'Microsoft Office\Office15\Library' or in folder 'Microsoft Office\Office16\Library'. Is there a way to automatically change the reference to that version, which is installed? Otherwise an Workbook which has been upgraded won't work on the older version anymore. And for the migration time we have teams working with the same workbook/database files on different versions of Office.
